Plastic crushing system with anti-blocking function and high in reliability

Abstract

The invention relates to a plastic crushing system with an anti-blocking function and high in reliability. The plastic crushing system comprises a crushing device. The crushing device comprises a body, a feeding pipe, a screen, a collection case and two crushing mechanisms, and further comprises a pushing mechanism and a knocking mechanism. The pushing mechanism comprises a connecting plate, a connecting rod, two press plates and two reciprocating assemblies. The knocking mechanism comprises a connecting assembly, a rotating shaft, a rotating wheel, two first bearings, two torsion springs andmultiple knocking rods. According to the plastic crushing system with the anti-blocking function and high in reliability, through the pushing mechanism, plastic blocked in the feeding pipe can be pressed into the body, and therefore the situation that too much plastic is placed to block the feeding pipe is avoided; and through the knocking mechanism, knocking work is carried out on the screen, sothat the screen shakes, and therefore crushed plastic can be fall into the body through the screen conveniently, and plastic which is still large after crushing can be shaken into the collection case.

Description

technical field [0001] The invention relates to the field of crushing equipment, in particular to a highly reliable plastic crushing system with an anti-blocking function. Background technique [0002] Plastic shredders are used to shred waste plastics and factory plastic scraps. Plastic shredders are widely used in waste plastic recycling and recycling of factory scraps. The motor power of the plastic crusher is between 3.5 and 150 kilowatts, and the rotation speed of the knife roller is generally between 150 and 500 rpm. The structure can be divided into tangential feeding and top feeding; the knife roll has the difference of solid knife roll and hollow knife roll. [0003] When the existing plastic crusher is unloading, if too much plastic is put into the feeding pipe, it will easily cause the feeding pipe to be blocked, and the plastic needs to be pushed into the main body manually, thereby increasing the chance of the staff contacting the saw teeth. The safety and re...

Problems solved by technology

[0003] When the existing plastic crusher is unloading, if too much plastic is put into the feeding pipe, it will easily cause the feeding pipe to be blocked, and the plastic needs to be pushed into the main body manually, thereby increasing the chance of the staff contacting the saw teeth. The safety and reliability of the existing plastic crusher is reduced. Not only that, the plastics crushed by the existing plastic crusher are of different sizes, and those that are too large cannot pass through the screen, causing large pieces of plastic to accumulate on the screen and block the screen. net, so that the smaller ones cannot pass through the screen, which affects the normal operation of the equipment and reduces the practicability of the existing plastic crusher
